I'm doing something very odd this week: speaking at the annual conference of Croplife America, the main trade group for the US agrichemical industry. Croplife members include Monsanto, Dow, Bayer, and Syngenta, all massive multinational companies I write about regularly and witheringly. I am astonished that Croplife wants to hear what I have to say—what I think of the group's member companies and their products is a matter of public record—and am curious to hear what they have to say to me.
